T 0 all whom it may concern:

Be it known that I, DENNIS F. Dnrrn, a citizen of the United States,residing at Newbern, in the county of Craven and State of NorthCarolina, have invented certain new and useful Improvements inCultivators, of which the following is a specification.

My invention relates to cultivators, and particularly contemplates theprovision of a simple compact and readily adjustable constructionembodying novel and elastic connections for supporting the soil workingdevices.

In the accompanying drawings, illustrating my invention, and forming apart of this specification, like numerals are used to designate likeparts throughout the several figures, and Figure 1 is a side elevationof my improved machine. Fig. 1" is tfl'Ollt end elevation of one of thebeams for supporting the soil working devices. Fig. 2 is a centralvertical longitudinal sectional view taken through my improved machine,with the wheels, their axles, and the soil working devices removed. Fig.3 is a rear elevation thereof with the rear cross bar of the main framebroken away adjacent the side bars of said frame. Fig. 4 is aperspective view of amodified form of axle standard, and Fig. 5 is aplan view of the machine.

In the practical embodiment of my invention, I provide a horizontalrectangular frame comprising side members .1, and a rear transverseconnecting bar 2, said side members 1 being angularly bent at theirforward ends, and converging inwardly to a longitudinally central pointof the said frame, and connected at their ends to the rear end of thedraft beam 3. Extending transversely of the said frame, inwardly andparallelwith its rear bar 2, is a supporting bar 4. Depending from theside members 1 of the frame, in alinement with the transverse supportingbar 4, are standards 5 provided with transverse tubular portions 6, forthe reception of short wheel axles 7 upon which are mounted the wheels 8at the sides of said frame. The standards 5 are also provided withlongitudinally extending ribs 9 to support their said tubular portions6, to which ribs, adjacent said tubular portions, are connected the endsof a supporting arch member 10, which is centrally secured to thetransverse supporting bar 4.

Mounted to slide vertically through brackets 11, upon the side members1, and extending parallel with the depending standards 5, are guide bars12, to which, at their lower ends, are attached horizontal diagonallyextending beams 13, having central vertical portions 14 bolted to saidguide bars 12, and each provided with spaced vertical tubular members15, in its length, rearwardly of said portion 14, for the adjustablereception therein of the soil Working device shanks 16. Upon theirforward ends, the beams 13 are provided with relatively short extensionbars 17 projecting inwardly at right angles thereto, and adapted for thereception of a slide bracket 18 adjustable thereon, and formed toreceive adjustably therein, the shank 19 of a suitable soil workingdevice such as a clod breaking spider disk 19*, which may, by thisconstruction, be adjusted laterally of the machine for a short distance.

In their vertical adjustment, the beams 13, bear against the innersurface of a depending extension piece 20, of the standards 5, belowtheir tubular portions 6.

Depending from the side members 1 of the frame, forwardly of thestandards 5, are standards 21, which are supported by diagonal bracebars 22 connected to, and extending between the lower end of thestandards 21 and the side members 1. To

the lower end of standards 21 are pivotally connected the forward endsof pivot supporting bars 23, provided with inwardly offset rear ends 24,pivotally secured to an ex tension 14 of the central portion 14 of thebeams 13, to further support said beams in their vertical adjustment.

In order to vertically adjust the beams 13, I provide vertical levers25, pivotally mounted at their lower ends upon the side members 1 of theframe, and provided with forwardly angular extensions 26 adjacent theirpivot,

which extensions are connected by a connectin rod 27 to the said beams13, said beams belng provided with apertured lugs 28 through which thelower end of said rods loosely extend, and are provided with nuts 29therebelow. The rods 27 are further provided with rigid sleeves 30adjacent their upper end, and with metal springs 31 mounted thereaboutand extending between said beam lugs 28 and the said rigid sleeves 30,thereby forming an elastic support for said beams 13, whereby the samemay move vertically against the tension of said springs, during theoperation of the soil working devices carried thereby. The beamoperating levers 25 are provided with latch mechanisms 32 for engagementwith the notches of a quadrant 33 secured to the side members 1 adjacentthe lower end thereof.

The drivers seat 34, is mounted at the rear end of the frame, upon asupporting bar 35 secured to and extending from the rear transverse barthereof.

It will be understood that by changing the soil working devices shown inFig. 1, for other devices such as solid wheel disks the machine may beconverted into a lister or side dresser.

Referring now to Fig. 4, I provide the axle standards 5 in upper andlower sections 60 and 61 respectively, the upper section 60 beingprovided with a vertical tubular portion 62 at its lower end, while thelower section 61 is provided with a horizontal tubular portion 63, whichreceives the wheel axles 7, and is supported by a vertical rib 64, saidlower portion being also provided with a vertical post 65 projectingupwardly through and above said tubular portion (32 of the uppersection, and forming thereby, a pivot upon which said lower axlecarrying section may be rotated to guide the wheels in rough places. Theposts 65 of each of the axle standards are provided with angularinwardly extending foot levers 66, secured thereto above the tubularportions 62 and extending inwardly, whereby the operator may rotate suchposts to guide the wheels. In order that the rotation of the posts 65will be uniform at both sides of the frame, I provide the same withlevers 67, extend ing forwardly therefrom and secured thereto above footlevers 66, which levers 67 are pivotally connected at their forward endsby a connecting rod 68. In this form, the supporting arch member 10 maybe secured at its ends to the upper sections 60. Thus the standards 5,shown in Figs. 1 and 3, may be removed as a whole, and standardsconstructed as shown in Fig. 4, may be connected to the frame bars 1 ofthe machine in their place, when operating with the machine upon unevenor hilly ground.

Having fully described my invention, I claim:

1. In a machine of the character described, the combination ofa frame,depending standards secured to said frame and provided with transt ersetubular portions for the re ception of wheel axles, vertical adjustablebeams mounted below said frame, adjacent each of said standards, soilworking devices mounted upon said beams, and connections between saidframe and said beams for adjusting the latter, said standards havingextensions below said tubular portions, forming guides for said beams,in their adjustable movement, substantially as described.

In a machine of the character described, the combination of a frame,depending standards secured to said frame, and provided with transversetubular portions for the reception of wheel axles, vertically adjustablebeams mounted below said frame, soil working devices mounted upon saidbeams, elastic means for supporting said beams to permit of the verticalmovement thereof during the operation of said soil working devices, andconnections between said frame and said beams for adjusting the latter,said standards being provided with extensions below their said tubularportions, forming guides for said beams in their adjustable movementagainst the inner faces thereof, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
